a deep, throbbing, persistent ache. my doctor diagnosed it as fibromyalgia, thought to be the result of overactive nerves that cause chronic widespread pain. lyrica is believed to calm these nerves. i learned lyrica can provide significant relief from fibromyalgia pain. and for some people, it can work in as early as the first week of treatment. so now i can do more of the things that i enjoy. lyrica is not for everyone. lyrica may cause serious allergic reactions or suicidal thoughts or actions. tell your doctor right away if you have these, new or worsening depression, or unusual changes in mood or behavior, or any swelling or affected breathing or skin, or changes in eyesight, including blurry vision or muscle pain with fever or tired feeling. common side effects are dizziness, sleepiness, weight gain, and swelling of hands, legs and feet. don't drink alcohol while taking lyrica.
